Answer 1

Answer:

Step-by-step explanation:

Interest received per annum if entire 9000 given @ 4% = 360

Interest received per annum if entire 9000 given @ 7% = 630

Actual interest received per year = 2325/5 = 465

Now, apply the Principle of Alligation:

The amount of Rs 9000 will be divided in the ratio 165:105 or 11:7

9000 x 11/18 = 5500 @ 4%

9000 x 7/18 = 3500 @ 7%

Check :

5500 @ 4% x 5 = 1100

3500 @ 7% x 5 = 1225

Total interest = 1100 + 1225 = 2325
